cylindrical mold generator (remixed)

This is a butchered version of the original credited mold generator,
It's designed to save time and material (filament) when creating molds of cylindrical or semi cylindrical objects by the removal of the mold corners and sizing the mold to much closer to the size of the object you wish to create the mold for.
Will make both halves of the mold.
Sample input and output files are included.

6/2/2017: Added a tapered cylinder mold generator scad file.
Saves even more filament when creating molds for roughly conical shaped objects.
Includes sample input file "traffic-cone-sample.stl"
